As a hunter, can I use a motorized vehicle on USFS or BLM designated trails in Big Game Units covered by the motorized hunting rule?

Only if the use is permissible in the exceptions in the motorized hunting rule.  For example, if motorized travel is allowed by the USFS or BLM, you may use a motorized vehicle to retrieve downed game or pack in or out your camping equipment.  However, you may not hunt while packing camping equipment.  It’s important that you know what specific type of motorized use is allowed for the area you are hunting.  Hunt Units with Motorized Hunting Rule: 29, 30, 30A, 32, 32A, 36A, 37, 37A, 45, 47, 49, 50, 51, 52, 52A, 53, 56, 58, 59, 59A, 66, 66A, 69, 70, 72, 73, 75, 76, 77, & 78.
